Along with the aggravation of market competition, mobile communications network capacity has become a key factor that determines operator's competitiveness.Promote network capacity, it is one of important goal of network operation that network capacity is rationally utilized.
Therefore, the accurate evaluation of network capacity is seemed to most important.Yet WCDMA network has soft capacity and multiple services characteristic, at the many factors that affects its capacity in addition, this makes the Capacity Assessment of WCDMA network become a difficult point.And WCDMA system heap(ed) capacity is subject to power influences larger, prior art is not considered the impact of power factor (PF).
Embodiment mono-
To this, the embodiment of the present invention proposes a kind of WCDMA network capacity appraisal procedure, and in conjunction with Fig. 1, the method specifically comprises:
101, obtain the Ti of bearer traffic of each measurement period of all communities in network to be assessed and described network to be assessed, the carrier transmit power P i of each measurement period of described all communities and the maximum configured power of each community.
By the collection to existing network data, can obtain telephone traffic, data traffic, the carrier transmit power P i of each measurement period of described all communities and the maximum configured power of each community of each measurement period of all communities in described network to be assessed and described network to be assessed.
Certainly, for the collection of existing network data, can gather by network management platform, can adopt other modes yet, the present invention does not limit this.
Optionally, the bearer traffic of the telephone traffic of each measurement period of all communities and data traffic each measurement period of all communities in described network to be assessed and described network to be assessed in described network to be assessed and described network to be assessed.
Concrete, the principle conversion that the telephone traffic of each measurement period of all communities in described network to be assessed and described network to be assessed is consumed according to equal-wattage is data traffic, in embodiments of the present invention, can to telephone traffic, convert according to the result of reality test.For example, the telephone traffic that produces 1Erl for a hour is dialed in single speech business, and to be equivalent to speed be that 50Kbps downloads the power consumption producing for a hour, i.e. 1Erl conversion for data traffic be 50kb/s*3600s=180Mb.
Certainly, it is data traffic by the telephone traffic conversion of each measurement period of all communities in described network to be assessed and described network to be assessed that the embodiment of the present invention also can adopt other modes, and the present invention is not specifically limited this.
After the telephone traffic conversion of each measurement period of all communities in described network to be assessed and described network to be assessed is data traffic, be added with the data traffic of each measurement period of all communities in described network to be assessed and described network to be assessed, obtain the bearer traffic of each measurement period of all communities in described network to be assessed and described network to be assessed.
For instance, suppose that under certain network to be assessed, the telephone traffic of Yi Ge community 1 in five continuous measurement periods is respectively 1.0Erl, 1.6Erl, 2.0Erl, 2.2Erl, 2.5Erl, conversion is respectively 180Mb for data traffic, 288Mb, 360Mb, 396Mb, 450Mb, this community is respectively 352Mb in these five data traffics corresponding to measurement period, 274Mb, 210Mb, 412Mb, 157Mb, data traffic and data traffic after the telephone traffic conversion of each measurement period of described community are added, obtain the bearer traffic of described community in five measurement periods and be respectively 532Mb, 562Mb, 570Mb, 808Mb, 607Mb.
According to identical way, can obtain described with the bearer traffic of other each measurement periods of community in critic network and the bearer traffic of described each measurement period of network to be assessed.
Certainly, measurement period can be 1 hour, can be also half an hour, can be also other times.The capacity that the present invention adopts the data of two above measurement periods to carry out network to be assessed is assessed.The concrete data of a plurality of measurement periods that adopt can be definite according to actual conditions, and the embodiment of the present invention does not limit this.
102, according to the Pi of each measurement period of described all communities and bearer traffic Ti, matching P-T curve, and according to curve, obtain the P-T function of each community.
By the Ti of bearer traffic of each measurement period of all communities in described network to be assessed, carrier transmit power P i with each measurement period of all communities in network to be assessed, carry out data fitting, each community in described network to be assessed obtains a P-T curve, corresponding, according to each community described in described P-T function, obtain a P-T function.
For instance, suppose that the carrier transmit power of described community 1 in described five measurement periods is followed successively by 9.38W, 9.75W, 9.84W, 12.70W, 10.30W, bearer traffic in conjunction with described community 1 at described five measurement periods, obtain five corresponding P-T points, according to these five points, simulate a curve, the result obtaining is straight line, and corresponding P-T function is: P=0.012T+3(1).
Certainly, for the P-T curve simulating, according to concrete condition, can be straight line, can be also a near linear, can be also other curves, the embodiment of the present invention does not limit this.
Wherein, by data fitting, obtain the process of P-T curve and P-T function, can complete by mathematical software, also can adopt other modes, certainly, for a person skilled in the art, by data fitting, obtain P-T curve and P-T function is the known technology of this area, the embodiment of the present invention repeats no more this.
It should be noted that, in general, the data volume that P-T curve needs is abundant, if data volume is crossed, I haven't seen you for ages exerts an influence to result, and, the data area of P-T curve will meet certain requirements, and a certain compared with in minizone if most data only concentrate on, the accuracy of matching curve out can exist certain problem.
Also it should be noted that, partial data may be invalid, and the curve completing for matching will be rejected partial data, and, because the variation of ground substance environment can cause the variation of wireless environment, so to regularly revise P-T curve.
For how according to described data acquisition more accurately P-T curve and P-T function be those skilled in the art's known technology, the embodiment of the present invention repeats no more this.
103,, according to the P-T function of the maximum configured power of described each community and described each community, obtain the target service amount of described each community.
Wherein, the maximum configured power of described each community can obtain from webmaster.Certainly be also not limited to adopt alternate manner to obtain.
According to the maximum configured power of described all communities, the maximum configured power of each community in described network to be assessed is brought in the P-T function of described this community, obtain the target service amount of each community in described network to be assessed.
For example, if the P-T function of network Zhong to be assessed community 1 be:
P=0.012T+3 （1）
According to the maximum configured power P of described community 1, the maximum configured power that is assumed to be 15W，Jiang Gai community 1 is brought in function (1), and the target service amount T that obtains this community 1 is 1000Mb.
According to this algorithm, can calculate successively the target service amount of all communities in described network to be assessed.

By the target service amount summing value of all communities in described network to be assessed, be about to the traffic peak that in described network to be assessed, all communities can provide and sue for peace, the maximum that obtains described network to be assessed can bearer traffic.
For instance, according to described community 1, obtain the method for target service amount, obtain the target service amount of described all communities.Suppose You Sange community in described network to be assessed, be followed successively by community 1, community 2, community 3;
The target service amount of community 1 is derived as 1000Mb by above-mentioned steps, according to identical step, suppose that the target service amount that obtains community 2 and community 3 is followed successively by 950Mb and 1200Mb, the target service amount of San Ge community adds up to 3150Mb, and the maximum that is described network to be assessed can bearer traffic.
105, ratio that can bearer traffic according to the maximum of the bearer traffic of described each measurement period of network to be assessed and described network to be assessed, assesses described network of network capacity to be assessed.
The maximum of the bearer traffic of described each measurement period of network to be assessed and described network to be assessed can bearer traffic be done to ratio, can obtain the carrying ratio of the traffic carrying capacity of described each measurement period of network to be assessed.According to this carrying ratio, can assess described network capacity to be assessed.
